Nope, goto is NEVER "required". Sometimes it's handy, but never required.
Even in almost 30 years of C and C++ programming I have never *HAD* to
use goto. Proper code structure eliminates the need (and reduces the
number of potential errors).
Now that's not to say I've *NEVER* used goto. But the number of times
I've used it can be counted on one hand. And then it's because I'm
doing device drivers or similar, where size and speed are important
(still true on some ARM devices).
